SHMS Survey data

SHMS Collimator/Sieve

  • The SHMS collimator/sieve assembly is located between the Horizontal Bender and the first quadrupole.
  • The SHMS collimator/sieve are made of Mi-TechTM Tungsten HD-17 (Density 17 g/cc. 90% W, 6% Ni, 4% Cu).
  • The SHMS collimator is a flared octagonal aperture with thickness of 2.5 inches.
  • There are two SHMS sieves. Each with thickness of 1.25 inches.
  • The sieves have the same hole pattern but one sieve has the hole pattern horizontally shifted by half the hole spacing.
  • Drawings of the collimator and two sieves.
  • The drawings show details of the sieve hole patterns and the collimator shape.

HMS Collimator

  • The HMS collimators/sieve assembly is located in 166.4 cm from the target in front of the first quadrupole.
  • The HMS collimators/sieve are made of Mi-TechTM Tungsten HD-17 (Density 17 g/cc. 90% W, 6% Ni, 4% Cu).
  • The HMS collimators are both a flared octagonal aperture with thickness of 2.5 inches.
  • There are two HMS collimators which are designated as the "larger" and "small" collimators.
  • Drawing of the small collimator. It is labelled as the "top" collimator in the drawing. The "center" collimator is the drawing was replaced by the present day large collimator.
  • Could not find a drawing of the present day large collimator.
    • The dimensions are front (back) opening in the horzontal direction are 4.575cm (4.759cm) along top of octagon and 9.150cm (9.518cm) at the vertical middle of the octagon.
    • The dimensions are front (back) opening in the vertical direction are 11.646cm (12.114cm) along side of octagon and 23.292cm (24.228cm) at the horizontal middle of the octagon.
  • The HMS sieve has thickness of 1.25 inches.
  • Drawings of the sieve.

Target

Spring 2017 KPP run

Fall 2017 run

  • Logbook entry on the Fall target configuration which has links to file describing the targets and their thicknesses and a file with the mechanical drawing of the target ladder.
  • BeO target was replaced by the "halo" cylinder target. Logbook entry with drawing of "halo" cylinder target.
  • Drawing of target ladder with cryo cells and solid target ladder.
  • Drawing of cryotarget cell with 2.5inch diameter and 10 cm long (after using insert entrance window). Used for separate LH2 and LD2 cells in ladder.
  • Drawing of cryotarget with 1.6 inch diameter for 4cm cell.
  • Drawing of cryotarget with 1.6 inch diameter for 10cm cell.

  • HMS and SHMS Collimator Control document.
    • See Collimator controls on How-to page
    • NOTE: Do not attempt a reset of the collimator controls unless you have reason to believe that the collimator has moved and have checked with the RC
